M2434, yes but as far as I can tell they may only work for 37 years, I have no experience longer than that
My RUGF uses dolomite gravel which is like crushed coral (kind of) the grain size is about the size of rice.
I doubt a fluidized sand filter run slow would give any benefit. It is designed to keep the sand in a state of flux and there will be no anerobic conditions to convert nitrate.
Waterkeeper, you must have paid attention in school.
I am retiring a week from thursday. I am taking that next friday off. What are they going to do? Fire me!
